Nik Wallenda speaks at a press conference after he crossed the Little Colorado River Gorge on a tiderope near the Grand Canyon on June 23, 2013. The two-inch (five-centimeter) thick wireline starting from a Navajo reservation just outside of the Grand Canyon National Park is suspended 1,500 feet (450 meters) above the ground (about 50 feet higher than the Empire State Building) and is 1,400 feet long (about the length of five football fields). US daredevil Nik Wallenda became the first man to cross the Grand Canyon on a tightrope Sunday, completing his latest record-breaking feat in just under 23 minutes.
